Application filed January 6, 1909.' Serial No. 470,924.

Be it known that. we, LORENZ F. MUTHER, of Newton, county of Middlesex, and State of Massachusetts, and WILLIAM M. of Lynn, county of Essex, State of Massachusetts, citizens of the Unitedv States, have invented certain new and useful IImprovements in Eyelet-Setting Machines, o f'which the following is a specification, reference being had to the drawings accompanying the same and4 forming a part thereof.

Our invention relatesI to eyeleting machines having a plurality of punching and eyelet setting dies for4 setting a plurality of eyelets at each operation of the machine.

The objects of our invention are to provide an eyelet setting machine for setting eyelets in fabrics, such as Woven or fibrous fabric, without thereo Afurther object of ourinvention is to -provide an eyelet.y setting machine capable of uniting fabrics of soft texture, such as woven or fibrous fabrics, to others of a hard substance, such as metal plates or pieces of different shapes and thicknesses by one or more eyelets inserted therein and used as rivets.

In the drawings accompanying this speci- CatiOm-Figure 1 is a front elevation of our'eyelet setting machine; Fig. 2 is a sectional side elevation of the same taken through line 2-2, Fig. l; Fig. 3 is a front elevation through line 3-3 Fig. 2; Fig. 4 is a sectional side elevation of Fig. 3; Figs. 5, 6, 7 and 8 are sectional side elevations of the punch and dies taken through line 4 4 Fig. 1, and show four positions of the punch and dies from the position where the eyelet is inserted and riveted to complete the op.

eration of uniting two or more pieces' of fabric; and Fig. 9 shows one type of fabric with a metal end which our eyelet setting.

machine' is designed to secure togetherA by eyelets.

The machine is provided with the base 1 andthe, frame 2. The frame 2 has a main bearing for the driving shaft 3, upon which are mounted the operating cams 4 and '5 and the eccentric 6. The purpose of these parts will be described more fully hereafter. `The machine is also provided with the usual type of hopper vfor containing the eyelets and feeding them to the raceways. The

Thisform of cuttingthe bers or threads` hopper (which is-not shown) is. mounted on the frame 7, which frame is provided with the slots 8 and 9 designed to cate longitudinally upon the bearings 10 and 11, and is held in position bythe bolts 12 and 13. The frame 7 is oscillated back and forth by means of the cam 5 which contacts with the roll 14 mounted onjthe lever 15, which lever is pivoted upon the pivot 16 and connected to the raceway frame 7 Aby the stud 18,' which passes through the slot 17; the stud 18 being secured in the frame connection causes the frame 7 to oscillate transversely with every revolution of the driving shaft 3 so that the raceway 19'will present an eyelet to the setting device at each cycle of operation of the maf chine, the eyelet being presented so that the setting device will pass throughit in its outward movement, as i upon the end of the setting device, as shown in Fig. 6, the raceway reciprocates longitudinally backward out of the path of the movement of said setting device` so that the eyelet can be carried' up and inserted in the work to be riveted together.

The top of the frame 2 is provided with a bearing 20 arranged to receive a reciprocating head 2l, which reciprocating head has mounted therein the perforators 22, 22, etc. The reciprocating head is provided reciprosshown in Figs.v 5 and 6. yAfter the eyelet has been talen` with a pivot-pin 23 lextending transversely through it to which the connecting rods 24,y

24, are pivotally attached at their upper ends, the lower ends of said connecting rods being attached tov oscillating levers 25, 25. These oscillating levers are in -turn secured to the shaft 26 which is revolubly mounted in a bearing 27 formed on the frame 2. The shaft 26 has secured thereto the lever 28 which has a roll 29 mounted on itsvouter end. The roll 29 is formed and arranged to slide freely in the cam-track 30 formed in the side of the cam 4, the cam being arranged so that every revolution of the shaft 3 causes a vertical movement of the reciprocating-head 21. The frame2 is also provided with guide-ways 3l, 3l to receive a vertically reciprocating-head 32. The vertically reciprocating-head 32 is moved up and down-by means of the eccentric 6 which is mounted on the shaft 3. This eccentric is provided with the eccentric-strap 33 surrounding the same having attached to it a lever 34 which is pivoted upon the shaft 26 near its center, its outergend 35 being provided with links 36 which are attached to `the reciprocating-head 32 by means of the pivots 37; so that with every revolution of the eccentric 6 thevertically reciprocating plunger 32 is moved up and down. The vertically moving head 21 has secured inits lower side a -plurality of punches 22 as is shown in Fig. 1 so that a verticalmovement of said plunger 21 causes the punches 22 to move downwardly toward a work-bed 38 so that they will pass through the holes 39 in same and perforate any fabric that may be placed upon said work-bed 38.

l 'In Ithe process of setting eyelets, the punches 22 which are tapering to a point are 'caused to pass down through the fabric, making a hole in the fabric by pressing the fiber ofthe fabric outwardly from the axis of the punch without cutting any of the fibers. Further downward movement of the punch causesit to. pass down through the fabric, as shown in Fig. 6, until its end lenters a depression 40 in let feeding plunger 41.

plun punc The eyelet feeding er 41 is ,hen moved upwardly with the 22, -carrying therewith the eyelet upon the end of the plunger 22.` The shoulder 43 of the plunger 42 contacts with the presses the eyelet up through the fabric, as shown in Fig. 8, until the head of the eyelet is iin' contact with the under face of the fabric; thereupon the cams operating the reciprocating block 32 cause the plungers 42 and 22 to approach each other and rivet the eyelet securely at both ends upon the upper and lower surfaces ofthe fabric, as is hereinafter described yin greater detail. After the ev the work t e plunger 42 remains stationary and theplunger 22 moves downwardly to rivet the upper end of the eyelet over the fabric, as is shown in Fig. 8. The eyelet Afeeding-'plunger 41 slides freely in a hole in the die 42 and is provided with the head 44 which rests upon the upper lend of a com- ,pre'ssible spring'45 sox that said feeding 'lun er 41 may be movedA `downwardly in t e die 42 compressing the yspring45 its downwar movement, as is shown in Fig. 8.

The punches 22 constitute both the punch and the riveting-die, the annular plunger 46 forming ythe riveting portion of thepunch.

In setting eyelets 1n fabric such :as is shown Vin Fig. A9, the holes in tlie metal 47 are unched before it is inserted' onr` the fabric 48, the holes being spaced thesame distance apart as Vthe punches-227.'. `In order to hold the metal and the fabric firmly, lit is -resser-foot that will come down upon the abric and firmly hold it upon the bed-plate 38.

head of the eyelet and' elet is pressed upwardly through ciprocating means for disengaging the 49 represents a presser-foot which is wide enough to embrace all the punches 22, the punches passing through holes 50 in the presser-foot. This lpresserfoot 49 is slidably mounted on the plunger 21 and has secured to it a block 51 by means of4 the screw 52.- This block is .arranged to receive spiral springs 53, 53, the lower ends of the springs being incased in recesses 54 formed in the block and their tension adjusted by means of the adjusting screws 51a, 51a. The upper ends of the springs press upwardly against a yoke 55, the yoke 55 having down-turned ends provided with slots 56, 56, arranged to receive screws 57, 57, to hold the yoke in place on the block 54. This yoke is provided with a roll 58 pivoted by a pivot 59 to the yoke 55. The roll is adapted to b ear against a cam 60 which is mounted on a shaft 61, the shaft 61 being oscillated by means of a crank with a wrist-pin 63 which engages in a hole in a pitman 64, which pitman is secured by the stud 65 to the plunger 21 in such manner that when the plunger 21 reciprocates up and down vertically, it partially rotates the cam .61 through said crank 62 and the connection 64, the cam being set to advance the presserfoot downwardly ahead of the punches 22 so that the foot will press firmly against the fabric 47 before the punches 22 enter the same to punch a hole. It also holds the fabric while the eyelet is pressed into the hole. When the hole has been punched, the

eyelet inserted and riveted, and the lungers 21 and 32 moved apart, the presseroot 49 is moved upwardly to the position shown in Fig. 5 to complete the cycle of `operation so that the work may be removed and another piece inserted in the machine.
